Open access

Open access materials can be viewed for free, but generally have other restrictions - for example no commercial use, no derivations, and (in some cases) no unauthorized distribution. The degree of "openness" can be star-rated according to meeting, or not, the four key criteria: there is no barrier to access for the reader, there is no fee demanded of the author/s, the copyright is nor forfeited by the author/s, and the work can be freely distributed[1].

On Appropedia, sometimes open access materials help to fill gaps where we do not yet have adequate open content resources. These are clearly marked with the {{open access}} notice, and categorized at Category:Open access pages - these are work ported to Appropedia for which there is no clear permission to A. reuse for commercial purposes or B. modify.
